Product Description:

• We are Songle original relay Size: 70mm X17mm X20mm (LxWxH) - Main chip: EL817, SRD-DC03V-SL-C - Work voltage: DC 3V/3.3V - Control 10A 250VAC, 10A 30VDC load Features - Instructions with the signal output; - Signal input port can connect microcontroller IO port, high level signal - Double power selection design anti-interference ability is strong, photoelectric isolation protection of high reliability - Current wide detection range:DC0-25V input - A diode current protection - Response time is less than 20 milliseconds - Relay long life can absorb 100000 times continuously - External connection use spinning crimping terminal, make connection firmer - With fixed installation hole, convenient installation,High Level Trigger:The relay module is triggered by high level signal, which can be input from microcontroller IO,Jumper Caps:You are free to select whether the relay and the signal share the same power supply or not by removing the jumper caps on the pins or not. It is recommended to share the same power supply, because that is more convenient for using.
